They are day and night.The "D" is Devi's name is for Dark.And the "L" is Levi's name is for Light. ^^

The dolls? When Devi first arrived, I just let him sit right beside Levi. And Levi looked like he was going "wtf! why he looks so much like me?!" Like he was unhappy and confused. And Devi leaned on Levi and hugged him the whole time O__O Now they don't do that anymore. xD
